What does UTFL stand for?

Use the force, Luke

UTFL is a Star Wars acronym that stands for "use the Force, Luke." It is used when texting and chatting online to encourage a person to think or try harder.

The phrase comes from Star Wars when Jedi master Obi-Wan Kenobi tells his apprentice Luke Skywalker to use the Force when attempting to destroy the Death Star. Also, if you type "Use the Force Luke" in YT it unlocks an Easter egg.
